RCA AP52X standby power flicker

[MIPS]

So for another project I gutted out what remained of what I assume was once an RCA rear projection set. Best I can find is the model AP52X/AP5X stamped in various places. Anything in the cabinet or on the boards that might or given me a solid idea of the make and model was too damaged by the weather to recover. It must of been out there for at least six months.

Anyways, after a good cleaning and time to dry it was reassembled and seems to be functioning fine aside from one thing. When the set is in standby mode the high voltage chirps and all the voltage status LED's flicker like the set powers up for a split second, then turns off. Even the Power LED does this. The moment you power the set on however it goes away and the set never slips up. Once you put it back to standby however it goes right back to doing it.
Seeing how it can come out of standby with no issues I'm assuming the standby power is fine however something keeps making it kick on and then remember it should be off or something. I got no ideas at the moment. You guys got any? Also, if anyone knows where I MIGHT find some form of service documents listing what that giant array of adjustments do, I'd love to see it.




Edited: Nope, it's a Hitachi set. See below.
